Yo bro where do i download maldives as well as joiplay if possibleAs I said it you can only play RPGM games on Android with this method. Games made using Renpy or Unity can't be played on Android using this method.
Also, winter Memories can be played using Maldives Player cuz it's a RPGM game. I'll test it and confirm it to you. I'll also post some 18+ RPGM games too :-)
HIf i sum up all you have to do is EXTRACT THE GAME and ADD it in MALDIVES. That's it, it's nothing that complicated
